Construction Services

We provide a full scale of underground & aerial constructions services.

City Approval

Once the fiber path is approved, Mainline Fiber partners with local contractors to begin the construction process.

Equipment Selection

We collaborate to select suitable networking equipment, like fiber optic cables, connectors, termination boxes, and active components (e.g., switches and routers). Our engineers ensure it aligns with capacity, reliability, scalability, and compatibility.

We assess expected capacity, bandwidth needs, and resource sufficiency by estimating subscribers, service types, and future growth.

Mainline Fiber offers in-house project management, overseeing fiber optic projects from planning to cost analysis. We partner with licensed engineering and construction professionals.

Site Surveys

Phase 2


All Contractors and utility employees are documented when on site.  We will provide a field inspection and documentation of all contractors work.

Fiber Optic Route

Fiber optic cable is installed along the approved route.

What type of fiber optic construction service do you need for your project?

Site Preparation

All existing utilities are required to mark their underground facilities to prevent damage. Contractors and utility employees arrive on site to mark the locations of existing lines in preparation for construction.

Drop Install

After the release date, customers will be contacted for an engineering appointment. The engineering appointment/drop install consists of connecting the mainline fiber from the road to a small box placed on the outside of the customer premises. 

Drilled holes in wood or metal floor joists.

Mounted D-rings for securing wire properly.

Pre-Wire Checklist

Cut sheet rock or remove false ceiling to run wire to unit.

Fiber placement along vertical risers on the interior of the building (MDF to IDF).

Placement of fiber through conduit or open riser from floor to floor.

Placement of fiber through conduit or open riser from floor to floor.

New pathway creation (placing conduit on building interior).

Core drill concrete walls and floors.

IDF and MDF room set up for Customer to Network interface.

Placed housings, including Modem racks and Power units.

Post-Wire Checklist

Line Installation

Physically install the fiber optic and copper lines, connecting them from the building IDF locations to the designated customer premises.

We handle the termination and routing of customer lines (Cat5, Coax, Fiber) as needed.

Let us take care of it.

Phase 2


Fiber Optic Splicing

Fiber splicing (Mechanical and Fusion)

With the rise of fiber-optic connections, mastering splicing is crucial. Two main methods are fusion and mechanical splicing. Integrators must grasp both to align with long-term goals, performance, and budget.


At Mainline Fiber, we employ cutting-edge testing equipment, including optical time-domain reflectometer (OTDR) testing. This method involves injecting optical pulses into the fiber, collecting scattered or reflected light to characterize the optical fiber. It measures splice loss, length, and detects faults, making it invaluable for cable integrity verification and new installations.

Effective Planning and Preparation



Mechanical Splicing

Our mechanical fiber optic splicing technique aligns two fiber optic cables precisely without a permanent bond. Using an alignment device and matching gel with similar refractive index, it enables seamless light transmission with a typical loss of just 0.3 dB (10%).

Mechanical splicing is ideal for quick and temporary cable connections during installation, as it offers easy disconnection without the need for expensive equipment.


Fusion Splicing

Mainline Fiber utilizes fusion splicing for a permanent connection between two fiber optic cables. It involves using a machine or electric arc to precisely align and fuse glass ends, ensuring minimal attenuation, typically around 0.1 dB.

Fusion splicing, when done correctly, creates a reliable joint with low insertion loss and minimal back reflection. This makes it the preferred choice for applications like long, high data rate connection lines that don't require frequent modifications.
